The objective of this trans-disciplinary, trans-regional and trans-periodical issue of Artl@s Bulletin is to confront a wide range of sources (catalogues, institutional archives, photographs, interviews, etc.), methods (qualitative, quantitative, comparative, multi-situated, cartographic, etc.) and areas of investigation (careers, movements, markets, etc.) in order to highlight the pivotal and problematic role of traceability in the spatial study of art.
